That code does not mean the sensor itself is dead, only that it may be. You can 'check everything' and still be in the dark, typically that is worthless english in a faulty car post. If you have a simple air leak in the hose after MAF that alone can do it.
Oh yeah man! I've had it checked plenty of times. Always says the same thing. I checked the air hose yesterday. Seems to be in good shape unless there is a super small hole that I cant see. Oh well lol, it doesn't seem to be messing with the car , i just want that damn light off
